tsunami

Seismic ocean surge

A tsunami is a series of ocean waves caused by underwater disturbances—typically earthquakes, but also volcanic eruptions or landslides.

These waves travel at high speeds across open water, then surge to devastating heights when they reach shallow coastal areas.

Figuratively, tsunami describes any overwhelming force or flood: a tsunami of criticism, a tsunami of debt.
